CLASS: IC: G03C001-72; B41M005-18; G03C005-00. APPLICATION: JP 80-139761 8 Oct 1980. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) A photothermog. process is claimed in which a photosensitive thermochromic sheet contg. the oxyindole deriv. I (R, R1 = N-contg. heterocyclic moiety; R2 = H, alkyl) and a polymer binder is imagewise exposed to UV light (250-400 nm) and subsequently heated to form images. Optionally, the thermochromic sheet is heated and then patternwise exposed to UV light. Thus, a film support was coated with a compn. contg. 3,3-dipiperidinooxyindole and poly(vinyl butyral) to give a photosensitive sheet for imaging process. 5149-74-6 is the cas registry number of certain chemical which is used as reagents here. .
